The Keep (1997) is the twenty-third soundtrack album by Tangerine Dream and their fifty-eighth overall. It is the soundtrack to the movie The Keep (1983). A limited run of 150 CDs were sold at a concert by the group in the UK in 1997. Virgin soon announced that the album would be available for general release in early 1998, but legal issues with the film studio stopped the release. In 1999, Tangerine Dream’s own record label sold 300 copies of the Millennium Booster album set that included The Keep with a different cover.
